Greetings Lexus Owners. I have a question about a oxygen sensor ( Bank 2, Sensor 1 ). The sensor needs replacing but, it’s difficult finding the exact / correct fit item at the big box auto supply store’s.

They have sensor’s in stock but, they don’t have them listed by ( Bank or Sensor ).

09 Lexus ES 350….

Thank you in advance.

 

Check "Rock Auto". Save yourself some money. Bank 2 sensor one is before your CAT. Plan on replacing both. Bank 1 sensor one also. Be breatful it's not sensor 2. That's a loa DC of fun! 🤣

Those are the two but I don't remember which is which, I'd have to check later if you don't figure it out. Make sure you have enough leverage to remove them...I stripped one and had to take it to a mechanic shop to remove it.

 

Thanks to you all for your assistance.
